Bacon Quiche

Directions

1. Preheat oven to 425°.
2. Weigh or lightly spoon flour into dry measuring cups; level with a knife. Combine flour, 1/4 teaspoon salt, 1/4 teaspoon pepper, and baking powder in a food processor; pulse 2 times to combine. Combine oil and 3 tablespoons water. With processor on, slowly add oil mixture through food chute; process until dough comes together. Turn dough out onto a lightly floured surface. Knead 1 minute. Press dough into a 5-inch disk; wrap in plastic wrap, and chill 20 minutes.
3. Roll dough into a 12-inch circle. Fit dough into a 9-inch deep-dish pie plate coated with cooking spray. Line dough with foil; arrange pie weights or dried beans on foil. Bake at 425° for 12 minutes or until edges are golden. Remove weights and foil; bake an additional 2 minutes. Cool on a wire rack.
4. Reduce oven temperature to 350°.
5. Cook bacon in a large skillet over medium-high heat until crisp. Remove bacon from pan, reserving drippings; crumble. Return pan to medium-high heat. Add shallots to drippings in pan; sauté 2 minutes. Add mushrooms and thyme; cook 10 minutes, stirring occasionally. Stir in spinach; cook 2 minutes or until spinach wilts. Remove from heat; let stand 10 minutes. Drain any excess liquid.
6. Place milk, half-and-half, eggs, egg white, remaining 1/2 teaspoon salt, and 1/4 teaspoon pepper in a blender; process until smooth.
7. Arrange half of cheese over bottom of crust; top with spinach mixture and remaining half of cheese. Carefully pour milk mixture over cheese. Sprinkle with bacon. Bake at 350° for 45 minutes or until filling is set. Let stand 10 minutes.
